Victron BlueSolar Polycrystalline Solar Panel 280W-20V (SPP042802000) – 1650×992×35 mm (Series 4a)

The Victron SPP042802000 is a robust 280 W polycrystalline solar module designed for reliable energy yield in off-grid, marine, RV and backup installations. Its low voltage-temperature coefficient helps maintain performance in warm conditions, while strong low-light sensitivity supports better harvest during cloudy mornings and late afternoons.

Key benefits

• Better real-world harvest: strong low-light performance and improved high-temperature operation. 

• Shade tolerant design: bypass diodes reduce power loss when part of the panel is shaded. 

• Built for outdoor use: sealed waterproof junction box, tempered glass, and anodized aluminium frame for easy mounting with common systems.

• Long warranty coverage: 5-year product warranty and power output warranty: 10 years at 90% + 25 years at 80%.

• Nominal power (Pmax): 280 W (±3%)

• Vmp / Imp: 31.9 V / 8.77 A 

• Voc / Isc: 39.13 V / 9.23 A

• Max system voltage: 1000 V

• Dimensions: 1650 × 992 × 35 mm

• Weight: 18.4 kg

• Operating temperature: −40°C to +85°C

• Mechanical load / hail: 200 kg/m² max load; hail rating 23 m/s (7.53 g)

• Connections: high-power models include a pre-wired quick-connect system with MC4 (PV-ST01) connectors.

Typical applications

Ideal for 12/24/48 V battery systems via an MPPT charge controller (e.g., Victron SmartSolar), as well as off-grid cabins, RVs, boats, telecom/backup and hybrid storage setups where durability and dependable yield matter.
